  • Monofuctional polyacrylates, their production and their use for the production of polycarbonates
    Patent number: 5109079
    Abstract: The invention relates to polyacrylates corresponding to formula (I) ##STR1## to their production in a quasi-ionic polymerization and to their use as monofunctional chain terminators, optionally in combination with typical other chain terminators, for the production of aromatic polycarbonates.The invention also relates to the polycarbonates or polycarbonate mixtures obtained using the compounds corresponding to formula (I) and to their use as additives for other thermoplastic polycarbonates.
